The investigator collected data on marketing of agricultural products ( particularly vegetables) in contemporary China, especially in Hebei, Henan, Zhejiang and Sichuan provinces. He investigated each system of their shipment, wholesaling and retailing under the planned economy in 1949-1978 and that under the market economy since 1979. The main results are as follow ;1. Under the planned economy in 1949-78 marketing of agricultural products are controlled by governments. Vegetables for marketing were produced mainly in the appointed production areas in suburbs of cities and distributed by state marketing organizations.2. Under the market economy since 1979 production and marketing of agricultural products has been gradually liberalized. Nowadays vegetable production areas are located even in remote places and long distance transportation of vegetables is popular.3. Assembling markets are developing in the vegetable production areas, but usually middlemen have control of price making. Lack of cooperative marketing makes farmers' position more weak..4. In large cities many wholesale markets are established. Most of them however are not good-equipped and extremely crowded during their trading hours.5. A lot of retail markets (so called free markets) flourish both in rural and urban areas and supply perishable goods to the consumers. Most of them are even now open-air markets and have some problems concerning sanitary and transportation.The investigator reported some of the results at 29th International Geographical Congress held in Seoul, Korea in August 2000 ; and at annual spring meetings of Association of Japanese Geographers in March 2000 and 2001.
